Application filed April 28, 1924. Serial No. 709,581.

To all whom z'tfmay concern:

Beit known that I, MICHAEL N.

SCHNEIDER, a citizen of the United States,

work required in the application of. they flashing, and on the other hand due to the fact that the flashing was notabsolutely waterproof, but whenv expansion or contraction of the roof relative to the wall occurred, such flashing would pull loose water to enter. l

Further than this, it was frequently the case that the flashing required special tools and skillful workmen and an inordinate amount of time for its application thus precluding its use in the majority-ofcases.

This invention is designed to overcome the above defects, and objects of such inven tion are to provide a flashing which/is absolutely waterproof, in which expansion or contraction of the roof will not openthe flashing, and which requires a small amount of material and no calking whatsoever in its application. i

Further objects are to rovide a flashing which may be most rea ily applied to a wall, chimney or similar member during the construction thereof, which will not cut or injure the workmen, which even in its ini tial stage of application, does not pro'ect outwardly a material distance and. inter ere `with the free working .of the wall, and

which may be easily handled in suitable length units. l

Further objects are to provide a flashing which is so constructed that the individual units thereof, althoughof material length, are rigid and will not flex or fold transversely, which is provided with a prominent counter flashing receiving groove, inwhich ythefgigrooves of successive elements are maintained in: alignment at all times, and which is so'constructed that when the roof is to be repaired-thel flashing may be readily manipulated `without disturbing its setting in the wall.

Further objects are to provide a flashing and permit.

' which is securely anchored in the wall, and

which, although the masonry may slightly loosen, will nevertheless,l prevent water from running over and under the flashing in the 'parts set in the Wall or, in fact, in the projecting part, which is of neat vand finished appearance, which requires a minimum amount of material and may be cheaply produced, and which may be set in a wall during the construction thereof ina simple and'easy manner, or may be applied to a previously constructed wall with a mini' mum of work. i i

embodimentvof the invention is shown in the accompanying drawings,`in which y,Figure l is a 4sectional view through a wall and a portion of thei roof showing the flashing in one stage of application, such view corresponding to a section on the line '1-1 of Figure 3.

Figure 2 is a correspondin view showing. the- 'flashing as it appears w en in finished condition.

p Figure 3 is a plan view of a joint between successive elements of the flashing.

'Figure 4 is an enlarged section on the line 4-4 of Figure 3.

vThroughout the specification and` the claims, the term wall will be used to designate what is commonly'known as a wall or a chimney, for instance, a masonry partition, or in fact any similar member.

The flashing comprises a main member of sheet metal which is provided with an upper portion l, an intermediate portion 2, and a lower portion 3. These portions are arranged in superposed relation 'by folds t andv 5. The bottom portion 3 terminates short of the outer end of the projecting parts l and 2, as may be seen from Figure l,` and is provided with a downwardly projecting positioning flange 6 which is adapted to abut against the face of the wall 'i'. The top plate l is provided with an upstanding anchoring and leak preventing flange 8.

sov

It is to be noted that even in this partially completed state, the projecting portion of `the flashing will not cutor injure the workmen or in' any way hinder their free Working around the wall. It is provided with a rounded smooth outer edge which will not, as stated, damage the workmen. It is also-relatively stiff and will not be distorted by even severe usage.

When the roofing material 11 is positioned it is folded upwardly as shown in Figure 1, and a counter flashing consisting of an angle shaped sheet metal member is employed at this stage. This counter flashing consists of an apron portion 12 adapted to contact with the outer face of the roofing material 11, and of 4an inwardly extending marginal flange 13 which fits within the groove formed between the members 2 and 3 of the main member.

It is to be particularly noted that this Acounter flashing inay most readily be slipped into position into the outwardly opened groove so that no alteration of the masonry joint is required for its application.

ftei` the counter flashing has been positioned the overlianging portion of the main member is folded downwardly over the apron portion 12 of the counter flashing, as shown in Figure 2; this locks the counter flashing in position and completes the joint.

These flashing members are made up in units of suitable length and may, if desired, be of considerable length without danger of bending or crinkling in handling, for the reason that the marginal flanges formed on both the main flashing member and counter flashing, reenforce the units against transverse folding and thus secure very .rigid and easily handled units. Where the wall is of considerable extent and it is necessary to employ a plurality of units, a splicing or aligning sheet or strip 14 is emplo ed, as shown 1n Figures 3 and 4. This a igning strip or plate is slipped into the inwardly opening groove formed between the members 1 and 2, and thus holds the counter flashing receiving Agrooves of successive members in accurate alignment. These -splicing plates may be providedwith an upstanding rear flange 15, as shown in Figures 3 and 4, to secure the utmost stiffness and permit relatively rough handling as well as to complete the anchoring flange 8 and revent any gap in such flange, thus maintaining the continuity of the anchor and leak preventing flange, however crudely the main member may be set in the wall.

It is to b e noted that the inner and outer fold 5 and 4, respectively, ef the main membei' provide a stiffening or reenforcing feature for the flashing and prevent the complete closing of the counter flashing receiving groove formed between the members 2 and 3 even if the workmen are careless in forcing successive tiers of the wall downwardly. There is sufficient spring in the mainmember when constructed in accordance with the disclosure of this invention to insure at all times the free entry of the marginal flange 13 of the counter flashing.

In the-practise of this invention, the main member and the counter flashing may be formed of any suitable sheet material, such for instance as copper.

It is fiirther to be noted that if for any reason it becomes necessary to remove a 'portion of the roof, the projecting. downin the wall is never disturbed after the 'flashing has once been positioned.

It is to be noted that the anchoring and leak preventing flange 8 securely locks the flashing in position in the joint in the jvall. It is further to be noted that even if this joint should crack in places and slightly loosen from the flange that any water following along this ,crack will be stopped by the upstanding flange 8 and leaking even under this extreme condition willbe prevented.

It is also to be noted that no discomfort, hindrance or danger is caused the workman when completing a wall within which this flashing has been positioned, for, as stated, even in its partially complete stage, as shown in Figure 1, the projecting portion has a round smooth edge and will not damage the workmen. Also this projecting portion extends outwardly only a relatively short distance and does not hinder the free working of the wall.

It is also to be noted that by means of the aligning or splicing plates 14 and by means of the positioning flange 6, that unskilled labor may be 'employed wheny positioning 1 llO accomplishes a number of heretofore iinposf sible results with regard to durability, as of position and application, freedom from leaking and freedom 'from `danger to the workmen that, nevertheless, this flashing j,

may be constructed in an extremely simple manner and that it also needs or requires a minimum amountofvmaterial. Thus it may be most cheaply manufactured and rapidly produced.

It is further to be noted that any expansion or contraction of the roof with reference to the wall will ,not pull the flashing loose and will not crack the mortar joint. The portions of the flashing will give slightly under excessive stresses and a rupture or opening of the flashing is wholly prevented even under the most disadvantageous conditions.

It is similarly to be noted that in its finished condition, the flashing presents a reenforced outer portion due to the double thickness of the downwardly turned part formed of the members l and 2, as shown in Figure 2, and that such flashing willnot be readily disturbed or injured.

Although the invention has been described in considerable detail, it is to be understood that the invention may be variously lembodied and is, therefore, to be limited only vas claimed.

bers having successive folds to provide an outwardly opening groove and an inwardly opening groove and having an outer marginal flange, aligning plates" adapted to fit within the innergrooves of successive members, and counter flashing having an apron portion and a marginal flange adapted to fit in the outwardly opening groove.

2. A flashing comprising a sheet metal member adapted zto be set in a wall and having an integral anchoring flange at its inner end and a projecting integral positioning flange at its outer end, saidvlatter flange being adapted' to Contact with the outer face of a wall, said member having an outwardly opening groove and an inwardly opening groove, and having an outwardly projecting portion located above said outwardly open# ing groove, an aligning plate adapted to be positioned within said inwardly opening groove andhaving a rear flange adapted to' contact with said anchoring flange, and a counter flashing having an apron portion and a marginal flange adapted to be positioned within said outwardly opening groove.

In testimony that I claim the foregoing I have hereunto: set my hand at Milwaukee, in

thev county of Milwaukee and State of Wisconsin.
